MAINTENANCE & TROUBLESHOOTING
This section describes how to:
• clean the lens
• clean the air intake dust filters
• replace the projection lamp
• replace the batteries in the remote
• use the security lock feature
• troubleshoot the projector
Cleaning the Lens
Follow these steps to clean the projection lens:
1 Apply a non-abrasive camera lens cleaner to a soft, dry cloth.
• Avoid using an excessive amount of cleaner, and don’t
apply the cleaner directly to the lens.
• Abrasive cleaners, solvents or other harsh chemicals might
scratch the lens.
2 Lightly wipe the cleaning cloth over the lens in a circular
motion.
3 If you don’t intend to use the projector immediately, replace
the lens cap.
Cleaning the Dust Filters
The dust filters catch dust and other particles in the air. If the fil-
ters become clogged, the projector does not cool properly and
may malfunction.
1 Turn off the projector and unplug the power cord.
2 Turn the projector upside down and remove the screws on the
filter doors.
